Fosi Audio TB10D 600 Watts TPA3255 Power Amplifier Home Audio Hifi Stereo Class D Digital 2 Channel Integrated Mini Passive Speaker Amp

This is a great little Amplifier and the sound quality is awesome. Especially for the price. If u need an amp for passive bookshelf speakers. This is the way...

I use this amp on my desk for a mini hifi system driving Micca RB 42 speakers. The amp has treble and bass tone controls to tune things in for my room. This amp represents very high value for the cost. I love it. Recommended.

Worked exactly as expected…

Bought it for my bose 301 Series V. I love it, the quality and the size of the device is perfect for my work desk

If you are considering purchasing a stereo Class D amplifier and you don't require Bluetooth, digital inputs or balanced inputs then the Fosi Audio TB10D is a great choice. The TB10D stereo amplifier, when paired with a small music streaming device such as one of the WiiM music streamers (also available on Amazon), becomes half of a shoebox sized streaming audio system. You would just need to add a pair of passive (non-amplified) speakers. The bass frequency response of the TB10D was noticeably absent when first powered on. After about a half hour of operation the bass finally showed up and all was good. I leave the TB10D powered on as the standby power draw is very low. [Update: I measured the standby power consumption of the TB10D. Plugged in, not switched on, 1.0 Watt. Switched on, no input signal, power consumption is 2.5 Watts.] Even though I know that the location of the bass and treble tone controls on the TB10D are reversed, as compared with most other amplifiers and receivers with the treble control being on the left and the bass control on the right, I routinely forget and grab the wrong tone control. The speaker binding posts are small and close together. This is not an issue as I use banana plugs when connecting the speaker wires to the TB10D. Note that there is no headphone connection on the TB10D for wired headphones. If you need a small, inexpensive good sounding headphone amplifier for wired headphones consider the Fosi Audio P2 headphone amplifier. The TB10D's available output power, ~50 Watts per channel when used with 8 ohm speakers, with the included 32V/5A power brick is adequate for use in my kitchen audio system. The case and power supply of the TB10D remained cool to the touch even after extended listening (I measured 72F). If you have a large room, lower efficiency speakers, or desire audio levels exceeding ~85dB you should consider a more powerful amplifier. You can change the supplied external power supply for one rated for 48V, however this will increase the overall cost as well as increase the operating temperature of the TB10D. Within its limitations as far as output power, input options (one pair of RCA connections, no digital inputs, no balanced inputs), outputs (one pair of stereo speakers), no Mono mode switch, no BT, no Sub out, no headphone connection or remote control, the Fosi Audio TB10D is a very good choice. I found the sound of the TB10D when powering 4 ohm, 6 ohm and 8 ohm speakers to be consistently smooth, full sounding and non-fatiguing with a variety of music even after prolonged listening. I assembled a complete 2-channel audio system of exceptional value that can fit in a shoe box. Each of these products is currently available on Amazon. I chose the Fosi Audio TB10D amplifier that is the subject of this review. I added the well reviewed, amazingly compact WiiM Mini music streamer. [Update: I chose a pair of Saiyin Passive Bookshelf Speakers, 2-Way Passive Speakers, 3.5" Woofer & Silk Horn Tweeter that are sold on Amazon. I can't say enough good things about this small desktop speaker; see my separate review of the Saiyin DS6700M speakers.] This system is capable of filling almost any size room in a home with great sounding music. The TB10D amplifier's tone controls and the WiiM Home app's equalizer settings can be used to adjust the bass/midrange/treble output of the speakers.

Excellent et très puissant, très bon son , je l’ai installé pour mettre 8 enceinte de 150 W autour de la piscine il chauffe même pas et le son est extraordinaire. si vous cherchez un ampli puissant, de très bonne qualité, à un coût très modéré, n’hésitez pas une seconde.

Was actually really blown away by this amp. It's my first time buying Class-D amplification. This thing sounds so clean and flat in general. No noise detected, no hum, no heat from the amp and I can't believe how much power comes out of this tiny thing. Treble and Bass Controls sound nice. Completely replaced my old bulky Stereo Amplifiers so I'll definitely buy another one to have for my other pair of Passive speakers. Compact, Clean simple great power amplification.
